JOHN nAYNEs, or PEMBROKE, MAINE.

MACHINERY FOR OPERATING FOG-BELLS.

Specification of Letters Patent No. 31,886, dated April 2, 1861.

To all whom it may concern:

Be it known that I, JOHN HAYNES, of Pembroke, in the county of Washington and State of Maine, have invented a certain new and Improved Mode of Operating Fog or Signal Bells by the Action of the aves; and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

In the drawings, A represents a hull, suitable for the purpose, in which is erected a frame consisting of uprights B, B, and cross piece C, and within which swings the pendulum device, consisting of pendent arms D, D, cross pivotedpiece E, and bottom weight F.

Between the pendent arms D, D, is a wheel H, supported in a frame G, G, attached to the hull A, one of the arms or spokes of the wheel is slotted out so as to permit of the cross piece a, to pass through the same as fully shown, in the drawings.

The wheel H, is grooved out for the reception of a band, chain or belt I, which passes around pulley J, on a shaft turning freely in bearings in a frame K. A bell L, is also hung t0 the shaft upon which The operation is as follows: The hull A, or its equivalent, being anchored in any proper position and manner, the action of the waves causes it to rock back and forth, whereby the arms D, D, are caused to swing back and forth on their hinged support E, in the top of the uprights B, B, thus causing the wheel H, to rotate partially on its axls in consequence of the piece a, passing through the slot in one of the spokes of wheel H, as shown in the drawings. As the wheel H, turns back and forth on its axis, the belt, chain, or band I, is caused to act upon the pulley J, and bell L, whereby the bell is kept constantly ringing.

F, is a weight attached tothe bottom of the arms D, D, to give the proper momentum to said arms to operate wheel H, and bell L. Theextent of the motion of the arms D, D, as they swing back and forth, can be limited if desired, by a chain, or rope (2, fastened to the same and to some part of the hull A, on the uprights, B. The slot in the spoke allows the cross-piece a, to move up and down freely as the arms D, D, which it unites, swing back and forth.

It will be seen that my invention" is not only simple, but very effective, since the bell will be rung whenever there is the least mo tion in the water, while the parts are not liable to get out of order. It will also be seen that the motion of the bell in a storm must be very ra id and violent, since a very slight motion 0 the wheel H, causes the bell to revolve back and forth very rapidly.

Ropes or chains maybe used to strengthen the uprights if necessary.

Having described my invention what I claim and desire to secure by Letters Patent, is:

The combination of the pendulum device D, E, F, wheel H, and bell L, with the hull fl, slilibstantially as and for the purposes set ort In witness whereof I have hereunto subscribed my name.
